NOTE: I learned some more about the Grid, I think the following is true, not sure:
* The Configuration Manager has two parts: a client part, the Configuration Manager Client (UI), and a server part, the Administrative Router; the Configuration Manager manipulates the runtime.xml.
* A Grid Agent is used to start nodes programmatically; there is one Grid Agent per host. Nodes are JVMs; the Node types are: registry, router, application.
* The Windows Service Infor ION Grid Bootstrap uses the Grid Launcher and Grid Agent to launch everything in the Grid at startup: registry, routers, applications, etc.
